The poo-in-a-box idea is not a bad one, but your packaging would have to be good or the post office might become angry with you.

There are companies that’ll “bronze” pretty much anything, including cowpats, but you obviously don’t want to pay that much.

The answer, of course, is right there in the picture you’ve chosen for this post – it looks not unlike the Japanese “Unchikun” cutesy-poo (see what I did there?) to me, and there are plenty of those products on sale in the usual Japan-o-novelty places.

The “lucky poo” idea is not a new thing, so you shouldn’t have any trouble finding a nice big shiny gold one to send to your lucky winners.
